To all whom it may concern."

Be it known that l, Wmnmrr S. Sorrow a resident of Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Combined Liquid-Separators and Mufflers, of which the following is a specification.

My invention relates to a device which separates oil or other liquid matter from the air discharged from a vacuum cleaning apparatus and at the same time permits of the expansion of the compressed air before bein 'scharged from the apparatus.

invention is particularly applicable to a movable vacuum cleaning machine adapted to be drawn about in public places and designed to prevent oil or other liquid waste matter being discharged from the machine and to reduce the velocity of the discharged air.

In the accompanying drawing,

Figure l is a side elevational view of a portion of a vacuum cleaning apparatus with my improved separator and mufler shown in vertical section. v

Fig. 2 is a front elevational view of the mufller pipe.

Referring now more particularly to the drawing: the vacuum cleaning apparatus comprises, in part, the cylinder 3 containing a blower (not shown) which draws air through the vacuum pipe line and appara tus, with which the pipe 4 is in communication. The air drawn through the pipe l passes through the cylinder 3 and is discharged through the exhaust port 5 into the receptacle 6 which is in communication with the exhaust port 5.. The casing 3 and receptacle 6 are mounted upon a suitable running gear, partially illustrated by the wheel 7 and adapted to be moved by the handle 8.

Within the receptacle 6 is a separating member 9, herein shown in the form of a pipe, one end of which opens into the exhaust port 5, extendin diagonally across the re ceptacle and wit its lower end resting partially upon the bottom wall of the recep tacle. A series of openings 10 are formed along the upper surface of the separating member 9. The receptacle 6 is provided with an exhaust port 11 and an exhaust valve 12 is connected to the receptacle 6 at the exhaust opening 11.

As before stated, a pump or other suction means within the cylinder 3 discharges not only air, but oil or other liquids that may be used for lubricating purposes and if some means were not provided for trapping such liquid, it would be discharged through the exhaust valve 12 into the atmosphere.

llt will be seen from the foregoing construction that the exhaust air passing out through the exhaust port 5 strikes the lower imperforate wall of the se arating member 9 and any liquid carried y the exhausted air will run down the inclined wall of the separating member and flow out of the lower end into the receptacle 6.

No special means are provided at the lower end of the separating member for allowing theliquid to pass out of the same since merely a loose fit where the separating member joins the receptacle is sufficient for this purpose.

he air passing through the exhaust port 5 is in a slightly compressed state and, as the valve 12 is open to the atmosphere, the air passin into the separating member 9 tends to f0 low the course of least resistance, thereby passing directly through the openings. 10 into the valve 12 and out into the atmosphere. It will be noted however that the receptacle 6 is somewhat larger than the separating member 9 so that the compressed air passing out of the separating member is permitted to expand and its pressure materially decreased before passing out through the valve 12. Thus not only oil and other liquid substances are trapped and thereby retained in the machine, but the discharge of the air therefrom is less audible and of such velocity as not to disturb persons that may pass near the apparatus.

Having now described my invention-l[ claim:

1. In a vacuum cleaning apparatus havan air suction member provided with an in exhaust port, the combination therewith of ltltl oil or other liquid material carried with the airinto said tubular member will cling to and run down said imperforate back.

2. In a acuum cleaning apparatus having an air suction member provided with an exhaust port, the combination therewith of a'frame forming an expansion chamber, a tube extending diagonally through said chamber from an upper corner to a lower corner thereof and connected at this upper end with said port, the lower wall of said Copies of this patent may be obtained tor tube being imperforate and the front wall thereof being perforate, whereby air directed into said tube from said port will be deflected by said bottom wall toward and through said perforate'wall and into said expansion chamber, said chamber having an outlet.
